Comparing 2 tables in Delphi 1.0 or Reportsmith(sql)

hi....

I need to comapre 2 tables of same format(one old, one updated) the field values being yes/no. I need to produce a discepency report where only the unmatched fields are displayed.

I have an idea :
Take field values from both tables and place them in variables in Delphi then comparing them and outputting the unmatched variables to a new tempororay table that is eliminated after this report is generated.

How would you suggest that I solve this problem. Should I use Delphi 1.0 or should I use Reportsmith for processing.

Yours Sincerely

I have another idea,
Define in one of the tables an calculated field. Then in OnCalcFields Event. Check the two fields and place the result in the calculated field.

procedure TForm1.OnCalcFields..........;
begin
Table2.FieldByName([NoMatch]).AsBoolean :=
(Table1.FieldByName([Value]).AsString <> Table2.FieldByName([Value]).AsString)
end;

After this filter this table on all the values with nomatch = true;

Look out! Two tables have to be in sync.

For making report, it depends. If you want to make a very beautifull layout, you should use reportsmith or Quickreport. But if you use reportsmith you have to deploy that program as wel with your own program. If you just want to have a print-out, I advise to use Delphi. With Delphi you can also make beautiful reports but that takes a little more time and isn't so easy.
Wich program to process? Depends on which you take to make your report.
But if yuo plan to use the results also for other processing, use D1. I don't know if you know it but you can also use sql in D1, not only in reportsmith.

Have fun,
